A nurse is monitoring a client following a coronary angiography. Which of the following findings should the nurse report to the provider?

Choice A reason: BUN or blood urea nitrogen 30 mg/dL is above the normal range of 10 to 20 mg/dL and indicates renal impairment or dehydration, which can be caused by contrast dye used during coronary angiography or blood loss during or after the procedure. The nurse should report this value to the provider and monitor the client for signs of acute kidney injury, such as oliguria, edema, or electrolyte imbalances.

Choice B reason: Sinus rhythm 95/min on a cardiac monitor is within the normal range of 60 to 100/min and does not indicate any cardiac arrhythmia or ischemia.

Choice C reason: Respiratory rate 12/min is within the normal range of 12 to 20/min and does not indicate any respiratory distress or hypoxia.

Choice D reason: PTT or partial thromboplastin time 25 seconds is within the normal range of 25 to 35 seconds and does not indicate any bleeding disorder or anticoagulant therapy.

Choice A reason: Passing of flatus is not a reliable indicator of colostomy function, as it can occur even when there is an obstruction or ischemia in the bowel.

Choice B reason: Stoma is pinkish-red is a sign of a healthy and well-perfused colostomy, as it indicates that the blood supply to the bowel segment is adequate and there is no necrosis or infection.

Choice C reason: Tolerating a clear liquid diet is not a specific indicator of colostomy function, as it does not reflect the amount or consistency of the stool output.

Choice D reason: Absent bowel sounds are not a normal finding for a colostomy, as they can indicate a paralytic ileus or a bowel obstruction, which can cause complications such as distension, pain, or perforation.
